Why it was refused

  1. The Local Planning Authority considers that the proposed rear dormer window, by virtue of its size, design, form, and positioning would introduce an alien and unsympathetic design feature which would be significantly harmful to the character and appearance of the application property, wider streetscene and would the Character of the Chapel Allerton Conservation Area. No clear and convincing justification has been provided in relation to identified harm, as required by the National Planning Policy Framework (NPPF), neither have any public benefits been identified which would clearly outweigh the less than substantial harm to the character of the Conservation Area. Therefore, the proposal would be contrary to policies P10, P11 and P12 of the Core Strategy, saved UDP policies GP5, BD6, and N19, policy HDG1 of the Householder Design Guide SPD, guidance contained in the guidance contained within the Chapel Allerton Conservation Area Appraisal and Management Plan and guidance contained in the National Planning Policy Framework.

From the council's decision notice.
